제목 Selective gas sensing chemiresistor by using thiolated ligand conjugation on MoS2 for pattern recognition of volatile organic compounds
초록 Many researchers expect that breath analysis method will facilitate personalized lung cancer detection kits as a commercialized goods. For the sensing platforms of volatile organic compounds (VOCs), chemiresistor is considered as a promising candidates, because of the high sensitivity, reliability, and cost-effectiveness. However, all the fabricated chemiresistors so far have been based on simple nanostructures, high operating temperature and depletion region of metal oxide. Here, we develop a VOC sensor that has high-selective sensitivity depends on the VOC molecules. For that we fabricated MoS2 chemiresistor and used conjugation of various ligands for the enhancement of gas sensing performances. This will be a promising approach to constructing a versatile sensor array, by conjugating and modifying the ligand materials for selective interaction with targeted gas molecules.
